In order to realistically visualize such participating media as cloud, smoke, and gas, the light transport process must be physically simulated inside the media. While it is known that this process is well described physically through the volume rendering equation, it usually takes a great deal of computation time for obtaining high-precision solutions. Recently, GPU-based, fast rendering methods have been proposed for the realistic simulation of participating media, however, there still remain several problems to be resolved. In this article, we describe our rendering techniques applied to enhance the performances and features of our GPU-assisted participating media renderer, and analyze how such efforts have actually improved the renderer. The presented techniques will be effectively used in volume renderers for creating various digital contents in the special effects industries.

This study was conducted to investigate the motives and effects of artists and teachers who participated in the ' Explore Life through Art' support project for school education by theme of culture and arts. As a result of research analysis using online survey and in-depth interview research method, it was found that both intrinsic and extrinsic motives have a complex effect on artists and teachers' motivation to participate in the project. As for the effectiveness of participating in the project, the trust between artists and teachers and the contribution of education were positive, but the trust and satisfaction with the institution were negative. In order to increase the effectiveness of the project, it is required to improve the operation and management of the operating institution. Motivation and effectiveness of project participation are important factors in improving the quality of a project, and it is hoped that this study will serve as a basis for practical discussions on the role of operating institutions and projects.

This study examines the digital era's fashion system and defines fashion leaders in the system. The study was based on a theoretical review and a research survey to verify the theoretical findings. The results are follows. The critical changes in the fashion system are expansion, cyclical direction and closer distance between producer and consumer. By inflow of media to a new channel, a layer of consumers was extended and the range of celebrities participating in the fashion industry has expanded dramatically. Simultaneously with the change from vertical communication to cyclical and interactive, the direction of communication was re-routed through diverse media. Crowd sourcing activated through two-way communication service has increased consumer opportunities to participate in production and consumption. Fashion leaders have changed significantly under this new system. The range of celebrities participating in the fashion system has increased and different fashion leaders have appeared. An interactive and cyclical fashion system has been established through media innovation; consequently, the influential power of celebrities and individuals for direct participation in the fashion system directly has increased significantly.

This is the research on the correlation between the marketing activities conducted by the companies participating in the overseas exhibitions in the exhibition and the satisfaction of the visitors. I have been able to obtain the following findings through the positive research on the satisfaction of the visitors to the overseas exhibitions. The research findings show that the external elements of the participating companies such as 'external appearances of booths, interior facilities and the atmosphere', 'designs of exhibits', 'size of the participating companies', and the publicity elements of the participating companies such as 'the degree of application of mass media', 'prior publicity of the participating companies', etc. among the marketing activities conducted by the participating companies in the exhibition affect the interest and repeat business deals of the visitors. The findings also show that the elements to induce the interest of the visitors such as the booth design and display of products where the participating companies may produce their unique image and the prior publicity to the visitors constitute the important elements of marketing. It has also been revealed that the visitors whose purpose of the visits are to purchase the products and to satisfy their interest in 'the events and contents of the events affect the interest and the repeat business deals of the visitors, among the interest and repeat business deals pursuant to the characteristics of the visitors. It has also been found that the visitors who have recognized the representative brands in the exhibitions affect the interest and the repeat business deals and the visitors who have visited the exhibition several times are more satisfied than the visitors who have visited the exhibition for the first time. The comparative evaluation of the degree of importance of the marketing activities of the participating companies before the visitors' visit to the exhibitions and the degree of satisfaction after their visit reveals degrees of satisfaction in the order of 'the booth staff's professional knowledge of the exhibits', 'foreign language proficiency and their techniques of negotiation and demonstration', 'designs of the exhibits (colors and packaging), 'prior publicity of the participating companies. Such being the case, the companies participating in any of the overseas should maximize the result of their participation in the exhibition by training their staff in the products and foreign languages and through the prior publicity. It has also been found out that "the atmosphere of the booth in the exhibition such as 'launching of new products', 'external appearances of the booth, layout of the interior facilities and the atmosphere and events of the participating companies affect the interest and repeat business deals of the visitors, among the factors for the satisfaction of the visitors. Therefore, it has been proven that the external factors such as the external appearances of the booth, display of the products, launching of new products and events producing the atmosphere of the booth of the participating companies among the marketing activities conducted by the participating companies, and the extent of the training of the booth staff and prior publicity are the major factors affecting the interest and repeat business deals of the visitors.

In this study, a process of re-creating Jindo Buk Chum, one of the traditional Korean arts, into digital art using various artificial intelligence technologies was proposed. The audience's emotional data, quantified through artificial intelligence language analysis technology, intervenes in various object forms in the projection mapping performance and affects the big story without changing it. If most interactive arts express communication between the performer and the video, this performance becomes a new type of responsive performance that allows the audience to directly communicate with the work, centering on artificial intelligence emotion analysis technology. This starts with 'Chuimsae', a performance that is common only in Korean traditional art, where the audience directly or indirectly intervenes and influences the performance. Based on the emotional information contained in the performer's 'prologue', it is combined with the audience's emotional information and converted into the form of images and particles used in the performance to indirectly participate and change the performance.

Natural convection and radiation heat transfer in a square enclosure containing absorbing, emitting, and isotopically scattering(participating) media is studied numerically using the finite volume method. Various numerical methods are employed to analyze the radiative heat transfer. However, it is very difficult to choose the proper method. In present study, a finite volume method(FVM) and a discrete ordinates method(DOM) are compared in rectangular enclosure. The SIMPLER algorithm is used to solve the momentum and energy equations. Thermal and flow characteristics are investigated according to the variation of radiation parameters such as optical thickness and scattering albedo. The result shows that the accuracy and the computing time of FVM are better than those of DOM in regular geometry.

Creative thinking appears even before it is expressed in language, and its existence is revealed through emotion, intuition, image and body feeling before logic or linguistics rules work. In this study, Lego is intended to present experimental child interactive content that is applied with a computer vision based on image processing techniques. In the case of infants, the main purpose of this content is the development of hand muscles and the ability to implement imagination. The purpose of the analysis algorithm of the OpenCV library and the image processing using the 'VVVV' that is implemented as a 'Node' in the midst of perceptual changes in image processing technology that are representative of object recognition, and the objective is to use a webcam to film, recognize, derive results that match the analysis and produce interactive content that is completed by the user participating. Research shows what Lego children have made, and children can create things themselves and develop creativity. Furthermore, we expect to be able to infer a diverse and individualistic person's thinking based on more data.

Purpose: To better understand the benefits and harms of engagement with online pediatric liver disease communities within social media. Methods: We conducted a survey of caregivers of children with liver disease participating in online pediatric liver disease communities within social media, as well as a survey of healthcare providers (e.g., physicians, surgeons, nurse coordinators) from this field to better understand the perceived benefits and harms of participation. Results: Among 138 caregivers of children with liver disease that completed the survey, 97.8% agreed social media was a good place to learn about patient experiences and 88% agreed it was a good source of general information. Among caregivers, 84.8% agreed social media helps them to better advocate for their child. While 18% agreed that the information over social media was equal to the information from their healthcare team and 19% neither agreed/disagreed, only 3% indicated they would use this information to change care without telling their provider; in contrast, among 217 healthcare providers, 55% believed social media may lead caregivers to change management without telling their team. Conclusion: Engagement with online disease-specific communities in social media yields several benefits for caregivers and, in contrast to healthcare providers' concerns, participation is unlikely to lead to problems including caregivers changing the treatment plan without first discussing these plans with their team. Openness between caregivers and medical teams about the role for social media can help to improve trust and maximize the potential benefits of engagement with these groups.
